Use of anti-histamines and steroids give a quick relief fromAllergy is the exaggerated response of the immune system to certain antigens (allergens) present in the environment.
It is due to the release of chemicals such as histamine and serotonin from the mast cells, triggered by IgE antibodies.

Drugs like anti-histamine, adrenalin and steroids quickly reduce the symptoms of allergy.
Hence they give quick relief from allergy.
